so have fears of potential chemical hazards.
The Houston-based company said it will not make any trade secret claims in the information it posts on the industry website FracFocus.org, starting with wells fractured on or after Oct. 1.
The process pumps water and chemicals at high pressure to break shale. Then sand is added to the mixture to prop open the fissures and let oil and gas flow up the well.
Along with horizontal drilling, the use of hydraulic fracturing, known more commonly as fracking, has opened up new shale fields across the United States.
Among the many chemicals used for fracking are hydrochloric acid, petroleum distillates and ethanol, according to FracFocus.
“The policy we are implementing today is consistent with our belief that we are partners in solving industry challenges, and that we have a responsibility to provide the public with the information they want and deserve,” Derek Mathieson, Baker Hughes chief strategy officer, said in a news release.
Baker Hughes will not detail specific product formulations but will disclose a single list of all the chemical constituents and their maximum concentrations.
As shale drilling boomed across the country — and in response to grass-roots concerns about potential environmental or health effects — the oil and gas industry launched FracFocus.org in spring 2011 as a national registry for companies to voluntarily report the composition of hydraulic fracturing fluids.
The Ground Water Protection Council and the Interstate Oil and Gas Compact Commission maintain the FracFocus website, which has information on more than 77,000 wells.
Texas has required operators to disclose the composition of fluids used in hydraulic fracturing on FracFocus since Feb. 1, 2012, but the law allows them to withhold the identity and amount of the chemicals as a trade secret.
The use of the trade secret exemption is widespread.
Of 12,410 instances of hydraulic fracturing in Texas between April 2011 and early December 2012, companies used terms such as “proprietary,” “secret” or “confidential” 10,120 times while reporting data on the FracFocus.org website, according to data collected by Pivot Upstream Group and analyzed by the San Antonio Express-News.
In the Eagle Ford Shale in South Texas, the trade secret exemption was used 2,297 times in 3,100 fracturing events.
In Texas, the only people who can challenge a trade secret claim are the landowner and someone who lives adjacent to him or her. State regulators also can challenge the use of the exemption.
In 2013, the Harvard Environmental Law Program's Policy Initiative criticized FracFocus, citing a lack of transparency.
This year, an Energy Department advisory board said companies were shielding too much information from public view in the FracFocus registry.
When the outdoor air is polluted, indoor air can become dangerous as well - since contaminants can build up over time. Electrocorp offers a wide range of indoor air cleaners for industrial and commercial applications that can help remove those contaminants, including airborne chemicals, fumes, gases, odors, particles, dust, mold, bacteria and viruses.
